The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described,illustrated in theaccompanying drawings and pointed out in the claims hereto appended.

In the drawings-Figure l is a perspective view of the running gearprovided with an automatic brake embodying the invention. Fig. 2 is areverse plan view. Fig. 3 is a longitudinal sectional View. Fig. 4 is adetail view of the slide and the guide plate. Fig. 5 is a detail view ofthe transversely disposed connecting plate.

Like numerals of reference indicate corresponding parts in all thefigures of the drawings.

1 designates a transverse bar secured to the rear hound of a runninggear and having fulcrumed on its lower face oppositely disposed brakelevers 2 carryingbrake shoes 5 at their outer ends and having theirinner adjacent ends connected by a transversely disposed plate 4provided at its ends with slots 5 to receive the pivot for securing itto the inner end of the brake lever, and having at its center a socket 6in which is secured the rear end of a connecting rod 7 by means of a setscrew 8. The set screw permits the connecting rod to be adjusted andincreased and diminished in length to adjust the brake, and the slots 5permit sufficient swinging of the brake levers to permit an applicationof the brake. The front end of the reach or connecting rod is providedwith a horizontally disposed cylindrical collar 9 slidingly mounted onthe lower portion of a vertical lever 10 which is fulerumed intermediateof its ends in a slot 11 at the rear end of the tongue 12, and which hasits upper end connected with atongue rod 13. The lower portion of thelever is rounded so that the lever 10 and the collar 9 will readily turnon each other to permit a cramping of the wheels of the vehicle to whichthe running gear may be applied. The upper end of the lever 10 isconnected bya link rod 14 with a slide 15 which has its front endconnected to the rear end of the tongue rod, and which has its sideedges bent inward on its lower face to provide ways 16 receivingupwardly extending side edges of a guide plate 17 secured to the upperface of the tongue. The rear end of the slide 15 is provided withlaterally extending ears 18 to which are connected front ends of staychains 19 which are arranged at opposite sides of the tongue and havetheir rear ends secured to the pivot or pintle 20 which secures the rearend of the tongue between the front hounds. The slide 15 is providedwith a metal supporting strap 21 having its front endperforated, andadapted to receive a pin for locking the slide rigid with the tongue tohold the brake shoes off the hind wheels during backing.

The tongue rod is arranged in suitable guides 22 and is provided at itsfront end with a sleeve 23 extended rearwardly at the top and forwardlyat the bottom and provided with a depending lug 24 adapted to be engagedby a neck yoke center, whereby the brake is applied.

The collar at the front end of the connecting rod is limited in itssliding movement, and is prevented leaving the lever by a stop 25consisting of an enlargement at the lower end of the lever 10.

What I claim is-- 1. The combination with a running gear, the oppositelydisposed brake levers carrying brake-shoes at their outer ends, of alever fulcrumed intermediate of its ends at the rear end of the tongueand arranged in the slot thereof and extending above and below the same,a reach rodhaving its rear end connected with the brake levers, and itsfront end provided with a collar loosely sliding on the lower portion ofthe lever at the rear end of the tongue, and a tongue rod connected withthe upper end of the lever at the rear end of the tongue, substantiallyas described.

2. The combination with a running gear, the

oppositely disposed brake levers carrying brake-shoes, of a lever 10fulcrumed on the rear end of the tongue and extending above and belowthe same and having its lower por- 5 tion rounded, a tongue rodconnected with IO of the lever 10 and adapted to turn on the lever topermitacrampingof substantially as described.

3. The combination with a running gear, of oppositely disposed brakelevers carrying the running gear,

I5 brake-shoes, the plate provided at its ends with slots and pivotallyconnected thereat to the adjacent ends of the brake levers and providedwith a central socket, a set screw mounted on the socket, and aconnecting rod having 20 its rear end arranged in the socket andadjustably secured to the plate by the set screw, substantially asdescribed.

4. The combination with a running gear, of the oppositely disposed brakelevers, the lever 10 fulcrumed on the tongue, a reach rod connected withthe lower end of the lever 10 and to the inner ends of the brake levers,a guide plate secured to the upper face of the tongue and havingupwardly turned edges, a slide having its edges bent inward on its lowerface to form Ways to receive the guide plate and provided at its rearend with laterally extending ears and connected with the upper end ofthe lever 10, the stay chains having their front ends attached to saidears, and the tongue rod connected with the front end of the slide,substantially as described.

In testimony that I claim the foregoing as my own I have hereto affiXedmy signature in the presence of two witnesses.
